Many motion blur factors have existed for a long time in film and video (e.g. slow camera shutter speed). The emergence of digital video, and HDTV display technologies, introduced many additional factors that now contribute to motion blur. The following factors are generally the primary or secondary causes of perceived motion blur in video.
Whether the video looks crisp or blurry depends on its reach. “If something isn’t watched for a long time — because the vast majority of views are in the beginning, we will move to a lower ...
The coverage technique involves shooting from more positions than will be used in the final film, allowing the director to choose shots during the editing process. This avoids the need to bring back cast and crew for later pickups and reshoots if the director is unsatisfied with the results from the camera positions that were originally planned ...
A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor affecting video quality. Algorithms for FRC are widely used in applications, including visual quality enhancement, video compression and slow-motion video generation.
YouTube said Tuesday that the police body camera video from the school shooting Monday in Nashville, Tennessee, would normally violate its policies.
Soon this problem resulted in a solution consisting in the adoption of a standardized way of choosing aperture so that each major step exactly doubled or halved the amount of light entering the camera (f /2.8, f /4, f /5.6, f /8, f /11, f /16, etc.), a standardized 2:1 scale was adopted for shutter speed so that opening one aperture stop and ...

Coded exposure solves the motion blur problem without the negative effects of shorter exposure times. It is an algorithm designed to open the camera's shutter in a pattern that enables the image to be processed in such a way that motion blur and noise are almost completely removed. [8]
